flying keel

[dylanwinter]

stumbled across this

it is a russian designer who has come up with a keel that is not in the water - a counterbalance

not sure what to make of it

Might surprise anyone who tries to pass close by, reminds me of the blades on chariot wheels

Only watched the first minute of video, but assuming there isn't a matching thingy on the other side, it's "just" a canting keel as used by racers for many years now. Perhaps it cants a bit further than others, but this kind of keel coming up out of the water is not unusual - several times a video has been posted of a guy in a dinner jacket climbing onto one from a jetski alongside a large yacht travelling very fast.

ah...no.... ... completely different concept I think

6 mins in he tells how in 1980s Soviet Russia he built what looks like a quarter tonner in his 2nd floor apartment and lowered the pieces onto the street before assembling it! He was also part of the team who built the Russian maxi Fazisi on a $100k budget.

Regarding the flying keel concept, my question would be how does the design deal with leeway? Is heeling down on a pronounced chine enough?

It seems like a refinement of the canting keel concept and given his track record of design it will be very interesting to see how it progresses with the wave piercing hull form,

IMHO, its just another passing 'clever idea'. I am sure us sailors can see a list of reasons why this is just a 'clever idea' rather than a practical, long lasting solution.

it does not apply to us of course

but for the nutters trying to get around the world asap......

If it's "flying" it's not really acting as a keel. It's merely a counter balance so why make it complicated as a canting keel. Why not just have a weight in the boat that you can poke out to windward with maybe a halyard/stay to the mast head?

 

[mainsail1]

Yes, reinvent the trapeze!

Precisely!

Or that bloke with two tons of water bag hanging from the masthead to heel his boat under a bridge.

Ah okay fair enough. Should be a pretty effective system then although as others have said, strictly for the round the world boys. I guess it's the natural progression of the canting keel.

 

[Madhatter]

It appears to be able to go from one side to the other guided by the out riggers ( and cable ?? )

or the international canoe

It is effectively doing the same thing as a body on a plank (as on the Canoe), but this can be scaled.

The boat has a daggerboard to stop leeway and create lift, and this is really just a counter-weight.

He's a clever guy and ahead of his time; a radical forward-thinker. He designed a dinghy years ago called the MX ray, which was a fabulous piece of design.

It's a canting keel that cants to 80°. Not exactly a new idea but a nice advancement on current design.

it is not really a keel - it is a counterweight

But why is the bulb so tiny? Compare the volume of the bulb with one of the crew. Even if it is made of spent uranium, a man on a trapeze would probably provide more righting moment. (I appreciate that this is probably a small-scale simulator of his round-the-world boat.)
